Shawn Mendes has premiered a brand new song and we’re freaking out

Shawn Mendes has finally kicked off his Handwritten World Tour (only two months til he comes to the UK, eek!) and during the tour’s date in New York at the Radio City Music Hall, he debuted a brand new track named ‘Ruin’.

And it seems that Shawn has kept to his word about switching to a more John Mayer-sounding second album, after tweeting him back in January:

. @JohnMayer what are the odds you cut a solo on a song of mine? Am i crazy?
